If Social Security were collected via a Flat Tax instead of a Regressive Tax, there'd be enough money to fund it till the year Sarah turns 100. Want to?

No, make it a Progressive Tax, like Income Tax, where the more money you make, the higher a percentage you pay.

No, leave it the way it is.

Yes: the way it is now, someone who earned $30k/year pays in 6.2% of their income while someone who earned $250k/year contributed just 2% of their income. A millionaire pays in 1/10th of *1 percent* of their income.
